Preface

Swift Essentials provides an overview of the Swift language and the tooling necessary to write iOS applications. From simple Swift commands on the command line using the open source version of Swift, to interactively testing graphical content on OS X with the Xcode Playground editor, Swift language and syntax is introduced by examples.

This book also introduces end-to-end iOS application development on OS X with Xcode by showing how a simple iOS application can be created, followed by how to use storyboards and custom views to build a more complex networked application.

The book concludes by providing a worked example from scratch that builds up a GitHub repository browser for iOS, along with an Apple Watch application.
